TIME LIGHT-EXTINGUISHEB.

' SPECIFICATION forming part of Letters Patent N0. 760,677, dated May 24., 1904.

Application filed September 10, 1902. garial No. 122,791. (No model.)

To all whom it may concerm v I Be it known that I, WILLIAM J. BROWN, "a

citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain'new anduseful Improvements in Automatic Time Light-Extinguishers; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the artflto which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to enable gas,

} electric, or other lights controlled by valves,

turn-buttons, cocks, &c., to be extinguished automatically at a predetermined time or mo-- ment, and thus save or avoid the trouble and loss of time involved in the hand-turning of said valves, &c., toextinguish the lights.

7 It is a common practice in cities for store.

keepers to exhibit their'goods in the evening after the close of business by means of illu'- minated windows at the street front of their stores, in which the goods'are displayed during the earlier hours of the evening or night and while the streets are still well peopled.

To save the cost of the gas, electricity, &c., the lights have beencommo nly extinguished at some time in the laterhours of the night,

and this has required the presence of some one to extinguish the said lights. This frequently rendered it necessary to travel a greater or less distance to the store at a late hour and involved considerable inconvenience and loss of time and oftentimesthe hiring of some one to perform the service.

By my improvements the lights can be extinguished at any desired predetermined moment automatically, and thus the loss and inconvenience above referred to is avoided.

Other conditions frequently arise in which my automatic time extinguishing devices may be employed with great advantage, but it is deemed unnecessary to detail them herein.

The invention consists in the time light-extinguisher and in the arrangements and combinations of parts of the same, all substantially'as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, n which likeletters of reference indicate corresponding parts in each of 'the several figures, Figure 1 is a front elevation of my improved device, certain parts being broken away to show the construction more clearly. Fig. 2 is arear view of the same. Fig. 3 is a sectional View taken at line an of Fig. 1. Fig. 4 is a sectional view of a gas-pipe and immediate connections with the valve or cook ducted to the light in any suitable manner.

At a suitable point on said pipe or duct is stationed a cock, valve, or turn-button Z), by

means of which the supply of fluid may. be cut off or broken and the light therefrom extinguished,-and 0 indicates a clock in connection with said cock, valve, or turn-button b and provided with means for turning or op-.

erating said cock, valve, or button at a predetermined time.

The details of the construction preferred are illustrated; but it will be understood that various changes or variations of construction may be employed under particular conditions without materially changing the invention or avoiding the essentials thereof.

Upon the'pipe a at a point near the clock- Work is fastened an arm 6d,; upon which is pivoted, as at e, a lever-like. pawl f, adapted to engage a tooth or stop. projection 9 upon the valve-stem to hold the valve open and permit a flow of gasto-the jet or in the case of a electric lampto hold the terminals of the electric circuit in contact to maintain the light. The said pawl f is held normally in its engaging position above referred to by means of a spring z', and the valve or turninga button'or cut-off for the illuminating fluid is automatically turned to effect the desired cut-off by a spring j, attached to a suitable fixture at one end the other.

Upon one of the wheels of the clockwork at a point eccentric to its arbor Z is fastened or formed a tripping lug or projectionlc, adapted to engage the arm of the lever-like and tothe-valve or cut-off at pawl opposite that engaging the stop or tooth g and throw said pawl out of engagement with said stop. Said tripping-lug 71; is preferably formed upon or secured to the escapement-wheel Z of an ordinary alarm appliance of a clock, said alarm being set by any suitable means common in the art, so as to operate when released at a predetermined time under the power of an alarm-mechanismcontrolling spring m, the power of which is transmitted from said spring an to the cogwheel a and pinion 0 to the said escapementwheel.

The alarm mechanism or appliance is controlled by the hour and minute train or trains of clockwork in any usual manner, so as to be released at any time desired to efliect an alarm (if desired and if the alarm-bell is retained) and a release of the spring-controlled cut-ofi valve. Ordinarily I prefer to dispense with the use of the alarm-bell, and for this reason the said bell is omitted from the drawings.

The tripping mechanism can be applied to any other suitable part of the clockwork to effect a tripping of the valve-stop or stay at or approximately at a predetermined or distant time.

To enable me to cut off the supply of gas or electricity prior to the time fixed upon, so that I can, if I should so desire, extinguish the light temporarily or otherwise prior to the time of automatic extinguishing, I have provided a finger-piece 19, having bearings adjacent to the pawl-lever f on the pipe (0 or any other suitable fixture and adapted to engage the lever and release the same from holding engagement with the lug, tooth, or stop 9.

' Said finger-piece is held up and away from the pawl f by a spring q.

The clockwork 0, governing the cut-off devices, is of any usual construction, and therefore it is deemed unnecessary to explain in detail the train of cogwheels and other mechanical elements transmitting, regulating, and controlling the power from the motor r to the hands 8 s on the dial 6.

Having thus described the invention, what I claim as new is 1. The improved light-extinguisher herein described in which is combined with the duct for the illuminating fluidhaving an arm fixed thereto, and a valve-cock or turn-button controlling the flow of said fluid and having a stop projection, a lever-like pawl pivoted on said arm and adapted to engage the said stop projection, a spring 5, holding the pawl normally in engaging position, means for turning the valve when released, a clock having a tripping-lug adapted to engage the lever-like pawl at a point opposite that engaged by the stop projection, substantially as set forth.

2. The improved light-extinguisher herein described in which is combined with the duct for the illuminating fluid having an arm fixed thereto, and a valve-cock or turn-button controlling the flow of said fluid and having a stop projection, a lever-like pawl pivoted on said arm and adapted to engage the said stop projection, a spring 1:, holding the pawl normally in engaging position, means for turning the valve when released, an alarm-clock having an escapement-wheel provided with a tripping-lug adapted to engage the lever-like lug,'substantially as set forth.

3. The improved light-extinguisher herein described in which is combined with a duct for the illuminating fluid, an arm fixed adjacent to said duct and a cock or valve controlling the flow of said illuminating fluid and having a stop projection and a spring for automatically turning said cook or valve, a lever-like pawl pivoted on said arm and engaging said stop projection to prevent the spring from turning said cook or valve, a spring for holding said pawl normally in engagement with said stop projection, and an alarm-clock having the escapement-wheel of the alarm mechanism provided with a tripping-lug adapted to engage the lever-like pawl and release the same from the stop projection, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this August, 1902.

WILLIAM J. BROWN.
